STARTING CONTROL CIRCUIT FOR NON-CONTACT IGNITION DEVICE FOR INTERNAL COMBUSTION ENGINE

Japanese Patent JP3481695

B2

PURPOSE: To simplify structure and to facilitate handling by interconnecting in series a first capacitor for charging, a diode, and a clutch switch and interconnecting in series a second capacitor for charging and a diode.
CONSTITUTION: When an internal combustion engine is started in such a state that the clutch of a vehicle is continued, since a clutch switch KS is in an ON-state, a first charge circuit 2 is brought into a closed state. A first capacitor 6 for charging is charged with a reverse voltage generated at a primary winding and a first switching element 3 is triggered. Since, through triggering of the first switching element 3, an ignition circuit is brought into a state not to effect ignition operation, drive of an internal combustion engine is impracticable. In this case, since a second charging circuit 4 is always in a closed state, a second capacitor 8 for charging is also charged with the reverse voltage of a primary winding. However, since it is insufficient to trigger a second switching element 5, the switching element 3 is triggered without an impossibility for it to be triggered by the switching element 5, and an ignition circuit is held in an inoperable state.
